Pregnant?!? Feedback please

How long did you wait to see a positive on your pregnancy test?? Has anyone waited more than 10 days to see a positive?? I am 8 days late with pregnancy symptoms but no positive. My doctor told me to come in on Tuesday so she can see me. She said sometimes it can take your body up to 12 months after birth control pills to get your hormones regulated and it might not show in a urine test for a while. But what I am asking is how long did it take to see a positive.  And did the pregnancy last?? Thanks. Much feedback is appreciated
